The Bay Area received rain over four days during the past week, although it was distributed unevenly — with the North Bay having more on some days and the South Bay getting wetter later in the week. With at least 10 days of sunny weather expected in the forecast through mid-October, dry conditions are back. And the light rain of the past week wasn’t enough to end fire season, experts say. But it was enough to clear out dust, smoke and other pollutants from the air and significantly decrease fire risk for a while. As is often the case, the highest elevations in the Greater Bay Area received the most rain.
